ORRV became MHHC years ago. It did a huge reverse split a couple months ago so that’s worth calculating too. At its height in the run before the ticker changed to MHHC it hit like .0049 so that 2000 shares would’ve been maybe $9.80 back then. It then dropped to trips shortly after. You should be able to figure out with that information what value (if any) is left and make your own decision.
Regarding your certificates, you should probably email/call the transfer agent to find out how to proceed with that.
